- Panels: 9-11 panels.
- Average daily production: 20-25 kWh/day.
For large homes (e.g., 8,000 kWh annually):
- System size: ~12 kW.
- Panels: ~21 panels.
- Data source: PVGIS (Photovoltaic Geographical Information System).
Adjustments Based on Sunlight Availability
The amount of sunlight a region receives plays a crucial role in determining solar system efficiency. Below is an overview of how sunlight hours affect system design:
Sunlight Adjustments by Region Table
| Sunlight Adjustments by Region | Sunlight Hours (per day) | Capacity Adjustment | Panels Needed (580W) | Notes |
|---|---|---|---|---|
| Germany | 3–4 | +20% | +3–5 | Subsidies help offset higher capacity needs. |
| France (South) | 5–6 | Standard | -2–3 | Excellent sunlight; standard setups suffice. |
| Spain/Italy | 6–7 | -10% | -3–5 | Strong sunlight reduces system size. |
| Nordic Countries | 2–3 | +30% | +6–8 | Seasonal sunlight necessitates robust storage. |
Description and Calculations:
For Germany:
- A 6 kW system produces 18-24 kWh daily with 3-4 sunlight hours.
- Panels required: ~12 panels, with 20% extra capacity to offset lower sunlight.
For Spain:
- A 6 kW system produces ~30 kWh daily with 6-7 sunlight hours.
- Panels required: ~10 panels, with reduced capacity needs due to strong sunlight.
